Its something on my Primary PC. My Surface Pro still runs fine and its DVDFab has been updated, but its iTunes hasn't. Unfortunately the SurfacePro is an older one so even removing DRM is slow. :(
I tried the steps outlined above on my primary PC, it didn't help. One thing I am noticing is iTunes sometimes doesn't start when I double click its icon (outside of using DVDFab). I'm not sure whats going on there. Using Apple's "full" Un-install instructions hasn't helped.

FIXED IT! It may (or may not) have had something to do with having iCloud installed once. I just remembered. My wife used to use an iPhone years back with MY ITUNES account. Her photos were all backed up to my iCloud account. When I got an iPad recently for work and didn't have enough space to back it up to iCloud, I figured I'd get her pictures off there (since they took up the bulk of the space). Since the web was limited to downloading 1000 pictures at a time I tried the Windows App to sync the photos. It didn't work properly (the app said downloading, made folders, but no pictures showed), so I un-installed iCloud.
So this time, BEFORE executing the steps in Post #1 above again... I installed/uninstalled iCloud from the Microsoft Store. Then ran through the steps in post #1, and my first movie as a test worked fine. NOTE: Apparently apps installed from the Microsoft Store are not listed in the Control Panel -> Programs and Features to uninstall them. So to uninstall iCloud, I just right clicked its Start Menu Icon and selected Uninstall from the pop up.
I purchased a few more movies (gotta love the MoviesAnywhere $5 sales!), so I'll try them later today and report back.
EDIT: Keep in mind that all this time, my Surface Pro kept running fine, and DRM Removal kept working. So while fixing my primary PC was on the "to do" list, it wasn't a priority, since the Surface worked.
